Chapter 27, Problem 27.21P
Interpretation Introduction

(a)

Interpretation: The product formed by Cope or oxy-rearrangement of given starting material is to be predicted.

Concept introduction: Cope rearrangement is a thermal [3,3] sigmatropic rearrangement. This rearrangement takes place in 1,5-diene to form more thermodynamically stable compound.

Sigmatropic rearrangements are pericyclic reactions which takes place by concerted mechanism. In these rearrangements, migration of sigma bond takes place.
